Be it known that I, JERVIS R. HARBECK, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Tube-Machine, of which the follow ingis a specification.

This invention relates to the construction of machines for convolutely winding a band of paper into tubes, of the type shown in my Patent No. 994,998, dated June 13, 1911, and its object is to provide a tube machine which shall have a plurality of duplex mandrels, thus giving it great capacity, both as to the length and the number of the tubes.

In the accompanying drawings, Figure -1 is an elevation of the front end of the ma chine. Fig. 2 is an elevation of the rear end of the machine. Figs. 3 and 4 together are an elevation of the left side of the machine.

The wlnding mechanism of this tube machine is supported'on main front and rear,

frames and the glue rollsand the devices connected thereto are mounted on base plates supported by brackets projecting main frames at the inner ends of the same. The. tube material is wound on two mandrels, being fed to them alternately by' a pendulum, and the mandrels are. each formed -of two parts, movable toward each other to form a 'complete winding mandrel, and from each other to finished tube. of the machine on the right in Fig. 4, that is, the elevation of Fig. 1, will'be considered the front.

The main frames at the front and rear of the machine are each formed of legs 1,2 and '3, top girders 4, bottom girders 5, and cross beams 6. The main shaft 8 iscarried in bearings 9 on the'crossbeams and may have a tight pulley 10 and loose pulley 11 at its rear end. On this main shaft are secured the gears 12 which revolve theman--v drels and glue rolls, and the worms '13 which engage the worm gears 14. which drive the slow moving parts, such as the gears which move the half-mandrels in and out, and the. various tripping and stopping de- The present construction is such that cycle of the machine; that the worm gears 14 make one-revolution at each cycle; and that the cam shaft 15 which is driven from a worm gear shaft 16 by the miter gears 17 and 18, revolves at the same speed.

Extending across between the top girders 4 are heavy hoods 20, in which are slidable,

'(Fig. 20). Within the the cylinders 21. cylinders are revoluble the shafts 22 having keyways 23 to receive the feathers 24 of the sleeves 26 and 27' respectively. See Figs.v

18 and 19. These sleeves are revoluble in the bearings 29, mounted on the cross beams guide plate, at

from the discharge the. In the drawings, that part "Patented June24, 1913.

31 which mesh withthe gears '12 on the main shaft and with the gears 32 on the sleeves 26. The gears 32 on the sleeves 26 also mesh with similar ears 33 on the sleeves 27 so that the sha ts 22 run at the same speed. All but one of these sleeves have collars 34 on their outer ends to prevent them from slipping out of their bearin s.

To slide the shafts 22 and the mandrels in and out, two cam disks 36 are secured to each cross shaft 16 and are provided with cam grooves 37 to receive the pins 38 on the levers 39. These levers are mounted on pivot shafts 40 and have segments 41 of teeth, at their upper ends, that engage the gears 42 on the shafts 44. (Fig. 20). Connected to these gears 42 are gears 43 engaging the rack-bars 45 secured to the lower sides of the cylinders 21.

The mandrels are in two parts 48, having cone-and-socket joints at their adjacent ends. They are grooved as shown in Fig. 21 so that the finished tubes may easily slip ofl. They are mounted on the hollow extensions 49 of the shafts 22, and are held in position by the screws 50. The shafts 22 and their extensions 49 are provided with holes 51. The cylinders 21 have nipples 52 to which lengths of air hose 53 may connect, which lengths also connect to the air valves. It should be understood that the mandrels run continually. During the time one mandrel is winding a tube the two halves of the other mandrel are moving apart and then together again. It may be assumed that six wraps of paper make a tube and that the shaft 16 makes one revolution to twelve revolutions of the mandrels, The two cam disks 36 on each shaft 16 are exactly alike but face outward, and their grooves are so formed that each lever 39 is at rest while the other swings out and back. While the paper is being wound, it is desirable that it be held against the mandrels. These are therefore provided with a cylindrical portion 54 which has suction holes 55, grooves 56 and cups 537. The paper is sucked into the cups and grooves so that the mandrel has a strong, grip onto the same.

The suction is provided by any desirable type of pump which connects at 60 to a pipe 61. (Fig. 1). This pipe connects to the valves 62. (Figs. 10 and 11). Within each valve body is a seat 63 and a disk 64 on the stem 65, which stem is guided by the head 66. A bracket 67 supports the lever 68, to the inner end of which -is connected the stem and to the outer end the bar 69 -which is supported by the pivoted arm 70.

A roller 71 on the free end of each link engages its respective cam disk 36, which has a cam flange 73. (Fig. 10). So long as the well as owest parts are as shown in Fig. 10, the suction of the pump keeps the disk off its seat and the pressure within the mandrel below normal. But when. the flange 73 engages the roller 71 and presses it outward, the disk 64 will be pulled onto its seat and the pressure within the mandrel returns to normal. It will be noticed that each valve is open while the pins 38 of the two levers 39 on that side of the machine are traveling in the circular portion of the cam grooves 37, that a is, while the two parts of the mandrel are joined. As the two portions of a mandrel move simultaneously, air valves at but one end of the machine are sufficient. If desired, both cylinders 21 of a mandrel may be connected to their air valve, or else the nipples 52 on the rear cylinders -may be plugged.

To assist in the discharge of the finished tubes, a collar75 is mounted on each half mandrel and is provided with teeth 76 which enter the grooves in the mandrel. A groove 77 in each ring receives a holder 78 secured to the adjacent hood 20. When the parts of the mandrel areseparated, a collar 75 engages one end of the tube and pushes it off that portion of the mandrel to which it adheres more tightly.

The feeding mechanism.-Extending upward from the inner ends of the front and rear frames are pedestals EEO/which carry the feed and cutting rolls. The paper band 81 passes freely to the machine up an inclined apron 82, which is supported in any desired manner, and then over and down between the cutting rolls 83 and 84, which are normally stationary, with the cut-away portion of the roll 84 toward the roll 83, and with the cutting "devices up. From over the roll 84, the paper passes down between the feed rolls 85, both preferably coated with rubber. Each is secured to a shaft 86 or 87, which shafts are connected together by gears 88 so that they will run toward each other at the same speed. The shaft .86 is mounted in stationary bearings in the pedestals 80,while the shaft 87 is mounted in the eccentric sleeves 89, (Figs. 25 and 26) which are mounted in bearings in the pedestals. To these sleeves are connected the slotted quadrants 90, by means of which the eccentric sleeves may be held in any desired position and the feed rolls properly spaced.

Connected to the shaft 86 is a miter gear 91 which meshes with the miter gear 92 at the upper end of the shaft 93. The bracket 94 (Fig. 4) supports bearings for the outer end of the shaft 86 and the upper end of the shaft 93, while a frame 95 furnishes a bearing for the lower end of this shaft as for the'stub-shafts on which are mounted the gears which drive the gluerolls. A shaft 96 is mounted in bearings carried by the frame 95 and by the frame 29 I which must always be such that the moves at. the surface speed of the mandrels.

' belts, it is that the cutting device is a thin blade 137 at the front end of the machine. These shafts 93 and 96 aregeared together by the bevel gears 98 and 99.

On the sleeve 27, which ,is driven by the mainshaft, is secured a pinion 100 by means of the screw collar 101.. This pinion meshes with an idler 102 on the stub-shaft .103 carried by the swinging frame 104. The frame is pivoted on the shaft 96. The idler 102 meshes with the gear 105 on the shaft 96. The diameter of the pinion 100 determines the speed of the feed. and glue-rolls,

The pendulum (Figs. 31, 32 and 33) v is formed of two similar portions, each com prising side bars 108 suspended from the shafts 86 and 87,\ami having shafts 109 secured in their lower ends. On these shafts are brackets 110 for the guide plates 111,l and the pulleys 112 for the feed belts 113, which belts also pass around the pulleys 114 on the shafts 86 and 87. The surface speed of these feed belts is the same as that of the mandrels.

As the paper passes down between the necessary that the lower edges of the guide plates 111 should be adjacent first to one mandrel and then to the other. Mechanism is thereforeprovided to swing the pendulum at regular intervals so that each mandrel receives the paperi-n its turn.

Mounted on the pedestals 80- is a shaft 118 towhich are attached the crank arms 119 which connect te-the pendulum by links 120. There is also attached the crank arm 121 having a slot 122 in which is adjustably secured the bolt 1 23, to which connects the upper end of the rod 124. This rod has a roller 125 near its lower end which rides inthe cam slot 126 inthe cam 127 mounted on the'disk 129 on the cam shaft 15, (Figs. 15- and 16). It will be noticed that this rod 124 has a flattened slotted end 128 so that it will be guided: on the cam shaft. The disk 129 has slots 130 through which extend the screws 131 which secure the cam and disk together in sucha manner that the time of the pendulum movement can be accurately determined. To prevent any lost motion, a cord- 132 passes over the pulley 134 carried by the apron 82, which cord connects to the weights 135 and to a lever arm 1191 As the band is wound into two tubes at each cycle, it is necessary to cut off two lengths of paper at each revolution -of the shaft 15. To do this, the rolls 83 and 84 are employed. It will be noticed in Fig. 27,

Loose end of shaft 142 is revoluble a cup-shaped gear 145 which meshes with the constantly running pinion 146 on the shaft e proportion between these gears is the same as that between the diameters of the rolls 83 and 85. Loosely the shaft 142 is ahub 147 (Fig.

29) which has a cam 148 on its outer end,

149 on its inner end, secured to a pedestal- 80 by a screw 150. See'Figs. 2, 3, and, 30.. Secured to the shaft collar 151 which has a shoulder 152 adapted to be engaged by the pawl 153 142 is the on the arm hisarm is loose on the hub of the gear 145- and is swung by the rod 155.

e gear 145 is a clutch-ring 157,

On the other arm 161 of this hubis p1v- 162 having a roller 163 at one houlder 164 whichengages the 165 of the clutch-ring.

of the constantly running gear 145. The

ear then carries the clutch-ring 157 and the hub 160 around with it, causing the cutters to perforate the band of paper at the end of one-fourth revolution, and continuing until the roller 163 gets back to the position shown in dotted lines. This permits the clutch ring to contract and frees the shaft from the gear.

The glue-applying mechanism.-Secured to the main end frames are brackets 175 which carry the troughs for the glue which troughs have outer sides 176, ends 177, hottoms 178 and inner sides 179. Beneath the troughs are steam heated boxes 180, by means of which the glue may be kept hot. J ournaled at the upper edges of the ends are the shafts 182 which have gears 183 at their front ends. The gear 183 on the left side meshes with the idler gear 184 on the adjustable stud-shaft 185 carried by the frame 95. (Fig. 5.) The idler 184 meshes with gear 186 on the stud-shaft 187; this with the gear 188 on the stub-shaft 189, and this with the gear 190 on the shaft 96. The gear 183 on the right side meshes with the idler 191 on the adjustable stud-shaft 192; this meshes with the gear 193 on the studshaft 194, and this in turn meshes with the As a result, the shafts 182 turn toward each other, as do also the rolls 209 mounted thereon.

As shown in Figs. 3, 4 and 5, plates 197 are pivotally mounted on the shafts 182 and are provided with segmental slots 198 through which the locking screws 199 extend into the ends 17 7; In Fig. 5, the plate 197, together with the rolls and gears mounted thereon, on the right-hand side of the machine, are shown swung outward, while the similar parts on the left-hand side of the machine are swung inward and mostly hidden by the gears 184, 186 and 188, and by the frame 95. Arms 200 on these plates assist in the manipulation. These plates 197 carry stud-shafts 201 on which are mounted the idler-gears 202 and 203 which transmit movement from the gears 204 on the shafts 182 to the gears 205 on the shafts 206. These shafts 206 are mounted in bearings vertically adjustable in the plates 197 by means of the screws 207. On the shafts 206 are mounted the glue-applying rolls 208 which engage the rolls 209 that dip into the glue 210 in the troughs. The roll 208 is preferably brass and the roll 209 a coating 211 of rubber.

Refer now to Figs. 6, 7, 8, 9 and 10 and accept that the glue-applying mechanism has been properly secured in position by the screws 199. Within the troughs and mounted on the shafts 182 and 205 of the rolls are auxiliary frames 212 which are adjustable by means of the bearings 213 and screws 214. In the upper ends of these frames 212 mechanisms may are slots 215, in which are adj ustably mounted the shafts 216 on which are-..-revoluble the guide-rolls 218. Screws 217 limit the movement of the shafts and guide rolls. Plates 219 extend between the frames and hold them properly positioned. Loosely mounted on the shafts 216, at the ends of the guide rolls are the gears 220 which mesh with the racks 221 on the edges of the aprons or shields 222. These shields are slidable in grooves 223 in the frames 212. The frames 212 carry shafts 225 and 226. On the former are collars 227 which separate the stripping knives 228. On the lat ter shaft are rings 229 to which the springs 230 connect, the opposite ends of the springs connecting to the arms 231 of the stripping knives and hold the upper ends of these knives against the rolls 208. Two separate be employed for smoothing down the paper onto the mandrel. Mounted in bearings 233 on the hoods 20 is ashaft 234 which has an arm 235 extending outward. (Figs. 2 and 3.) On the end of this arm is a rod 236 whose forked lower end extends down over the shaft 15. (Fig. 14;) A pin 237 on this rod enters the slot 238 in the cam 239. The concentric portions of the cam slot are each of such length that each rod 240 (Fig. 6) at the lower ends of the arms 241 is held against its respective mandrel during the finishing of the winding of the tube. The other device. is shown in Figs. 6 and 10. 245 extend between the cross-beams 246 near the inner ends of the end frames. A lever 247 connects to the shaft 244 near its front end, and to the rod 248. This rod connects to the plate 249 which is slidable on a bearing 250 on the shaft 15. (Fig. 12.) The plate carries a roller 251 which is held against the cam 252 (Fig. 4) by the spring 253. A. lever 254 is mounted on the shaft 245 near its rear end and connects to the rod 255 extending inwardly from the plate 256. (Fig. 13.) This plate also carries a roller 257, is slidable on a bearing 258 on the shaft 15, and has a spring 259 to hold the roller against a cam 260. (Fig. 3.) On the shafts 244 and 245 are secured the plate holders 262 which carry the presser plates 263 having slots 264 into which the knives 228 extend when the pressers are swung back. The operative portions of the ressers are rounded, as indicated in Fig. 7. lf desired, levers 265 may be secured to the shafts 244 and 245, (Fig. 6) and springs 266 to the levers, so that these pressers may always engage the tube material on the mandrels with the same force.

Operation-The paper is brought to the machine in large rolls or in any other desired manner, the only requisite being that the supply shall be continuous and at a constant speed. The end of the band is Shafts 244 and 4 passed) up along theapron 82,.over the roll S g-and down between the rolls .85 and belts 113. The operator next slides in the shield 222 tothe positionshown inaFig; 9, thereby liftingthe roll- 218 from the glue roll 208, and passes. thepaper down between .the roll 2l8;and.the shield until the the mandrel. The valve. in the main suction pipe isopened, which causes a current of air toenter the mandrel through the holes 55, carrying the end of the paper againstthe mandrel. \Themachine is then started and the mandrel will begin. to Wind up the paper as soon as the portion 54 of the mandrel reaches the paper. The shield. 222 is slid back which permits the roll 218 to press the outer side of the paper against the gluecovered roll 208. After about one wrap has been made on the mandrel, the cutter rolls cut the paper as explained above, and

shortly thereafter the pendulum swings toward the other mandrel. As will be seen in Fig. 6, this movement will cause the paper between the belts113 to be pulled out faster than the normal feed of the rolls 85, resulting in the paper being torn at the line of cuts. The new end continues down be-- tween the belts and is deliveredjust. in the rear of the roller 218 on the opposite side 80 of the machine, which carries itdown around the adjacent applying. roll 208. In order that the band of paper shall not continue to follow around the glue-covered roll 208, the knives 228 are provided; which '5 knives fit the surface of theroll and sepae rate the knlves and is immediately drawn against the mandrel by the air. As soon as the ,paper begins to wind onto the mandrel, the presser plate 2.63 is swung against the paper by the high. portion of the cam 252- or 260 acting on its. particular roller 251 or 257 rod 240 is. also pressed against the paper on the mandrel to assist in smoothing it down. After the mandrel has made the full number of turns. to wind the paper, the presser 268 and smoother 240 swing away from it, o. and the levers 39pertaining to that mandrel swing toward the ends of the machine, separating the two parts of the mandrel. But because of the collars 75, the tube is prevented from engaging either one of the stationary hoods, and falls as soon as the arts of the mandrel are fully separated. he two parts of the mandrel immediately reuniteso that by the time the winding of the tube on one mandrel is completed, the 1. other mandrel is ready to receive the paper.

During the winding, particular mandrel is open. Referring to Fig. 6, it will be noticed that the right guide plate 111 of the pendulum 5 is lower than the left. This is reversed end isadjacent paper therefrom. The paper is in-: clined toward the adjacent mandrel bythese Immediately thereafter the adj acent:

the air valve 62 ofthat' d when thependulum is at the other end of its stroke. It-has. the advantage. of pressing the; belts against each otherduring the feed by means of the links 270 on the; shafts 109. When, thependulum is swinging, the belts do .notpressagainst eachother, thus permitting the.- withdrawal of the fin l end of.- the tube material. The pressurebetween the rolls208- and 209 iscontrolled to a large extent'by the screws 207. Because. of the construction of the depressions 57 and grooves. 56 inthemandrels, an unusually strong grip is hadon the band ofpaper. When fewer wraps. of paper per tube are-desired, the size of. the gear is. reduced-L When-the same number of wraps aredesiredfor tubes of; larger'diameter, the. sizelof. this;
